COUPLING.

Application filed August 31, 1925. Serial No. 53,486.

- a fixed part and centering and maintaining A Fig. 3 is a side elevation showing a method of applying the invention to. a straight run the position of the cooperating parts throughout assembly thereof; and third, to couple the parts in a very simple and practical manner requiring but little attention on the part of the operator, and'by a device of great strength and relatively small cost.

My objects are attained by the construction illustrated in the accompanying drawings, in which: V Fig. 1 is a side elevation of an angle type coupling embodying the invention.

Fig. 2 is a central section of the angle type coupling.

coupling.

' The part 3- of the coupling is ordinarily connected to a. hose 3 by means of the exteriorly threaded male end 4, and the part 3 is provided with an intermediate flange 5 having a convex spherical or conical sea ting surface at (3. and a spigot end 7 projecting above said surface.

The cooperating part 8 of the coupling may be either an elbow fitting, as shown in Figs. 1 and 2, or a straight run fitting as shown in Fig. 3. It has an interiorly threaded female end 9 by which it may be connected to a pipe 9 so as to form a fixed part of the installation, the part 3 with. hose 3 connected thereto, being adapted to be hoisted into coupling engagement with the part 8 which is provided with a concave spherical or conical seating surface 10 at its other extremity. The bore of part 8 is adapted to receive the spigot end 7 of the part 3.

In the type shown in Figs. 1 and 2 the casting forming the part 8 is thickened at 11 and provided with an external concave bolt seat 12 in line with the axis of the end of the bore of part 8 which is adapted to receive the spigot end 7, and perpendicular thereto.

A ring 13 is adapted to slip over the displaceable part 3 of the coupling and engage the under side of flange 5; and a U-shaped yoke 14: has its extremities pivotally connected to the ring, as by cap screws 15. The yoke is tapped at its medial portion and provided with a convex ended eye-bolt 16 adapted for.

engaging seat 12.

The integral stop lug 18, exteriorly formed on part 8, is provided to assist in the quick positioning of yoke 1 1 in operation.

One method of applying my invention to straight run couplings is shown in Fig. 3. In this case two yokes are attached to ring 13, and opposite lugs 19 are provided on fitting 8 for seating the eye-bolts in a similar manner to that shown in Fig. 2.

A suitable hoisting medium such as a cable 20 may be connected to the eye of bolt 16, for elevating the part 3 and hose 3 relative to the member 8 which is a fixed part of the installation. Yoke 14: is turned to bring the same into proper position for swinging over the bolt seat 12, said turning of the yoke being accomplished without necessitating turning of part 3 and consequent twisting of hose 3*, since the part 3 is free to turn on ring 13. The freedom for relative turning between part 3 and ring 13, also permits turning of hose 3 when so desired, without turning yoke 14 out of alinement with its seat 12.

As member 3 and hose 3 are elevated, yoke 14 is swung to one side sufliciently to clear the member 8, while spigot end 7 is held in alinement with the bore of part 8 for relative telescoping of said parts. The arrangement is such that spigot end 7 will start to enter the bore of member 8 when the medial portion of yoke 14 is still an appreciable distance below its seat 12 or 19, and consequently as the elevation of the yoke is continued, the spigot end 7 forms a guide for alining the cooperating parts of the coupling, and when the cooperating seating surfaces 6 and 10 have been brought into proximate relation, the yoke 14 will have been elevated sufliciently for its medial portion to swing over seat 12 and 19. The abutment of bolt 16 against the bolt seat then supports the part 3 and hose 3 relative to the fixed part 8, so that relatively slight adjustment of the bolt will bring the seating surfaces6 and 10 into tightengagement and furnish the necessary compression for providing a leak-proof union.

The function of spigot end 7 is not only to assist in positioning the parts during assembly, but to maintain them in proper relation til) previous to tightening the eye-bolt. In this manner the coupling can be loosely made up and the part 3 turned as desired With referp Without ee r r dis l ement.

It is to be noted that the Weight of 13 and its attached yoke is sutficient to keep eyebolt 16 properly seated when once positioned with the side of yoke 14 against the stop l11g18,so thatbefore tighteningthe couplin the part 3 may be turned on ring 13 relative" to the lined member: 8, .Without danger o f displacing the ringandyoke.
